Massow’s video comes as Dame Tessa Jowell, who stood down as an
MP this year, officially launched her bid to become the Labour
Candidate.

She joins other Labour MPs Diane Abbott and Sadiq Khan, who have
both announced their intentions to run for the position.

“In many ways London is the greatest city in the world — a
byword for ingenuity, for tolerance and for optimism… My ambition
— our ambition — is to make London greater still. To build One
London, where every Londoner has the opportunity and security to
succeed, where Londoners have a quality of life to rival anywhere
in the world, where no Londoner is left behind,” Jowell said
at the London launch.

“One London, not the two we see so often today — where some
of the most severe poverty in the country is on the doorstep of
some of the richest places in the world.”
